Initially released on April 21, 2022, Ubuntu 22.04 LTS arrived with Linux 5.15 LTS kernel, which was later replaced by Linux kernel 5.19 from Ubuntu 22.04.2 point release. Now the third point release in this series, Ubuntu 22.04.3 LTS, is released with the Linux kernel 6.2 from Ubuntu 23.04 (Lunar Lobster). This version also features all security and software updates released since Ubuntu 22.04.2 LTS.

Furthermore, this release introduces a new hardware enablement stack (HWE) that consists of the Linux kernel 6.2 and Mesa 23.0.4. Other notable package updates are GNOME 42.9, LibreOffice 7.5.5, and Mozilla Firefox 116.
The ISO images for Ubuntu 22.04.3 LTS are now available for download from the official website. Those who wish to install the long-term supported Ubuntu 22.04 LTS series can choose this new installation media to avoid downloading lots of updated packages after the installation. Meanwhile, existing users of Jammy Jellyfish can update their installation by running the
sudo apt update && sudo apt full-upgrade command in the terminal.
In addition, new ISO images for each of the official Ubuntu variants are also available, including Kubuntu, Xubuntu, Lubuntu, Ubuntu Studio, Ubuntu Budgie, Ubuntu MATE, and Ubuntu Kylin. As these flavors are only supported for three years, compared to the five years offered for Ubuntu Desktop and Ubuntu Server, 22.04.3 is also the final point release for them.
Ubuntu 22.04 LTS will be supported till April 2027, in case you do not know. Next year will see the release of Ubuntu 22.04.4 LTS, which will include the kernel and graphics stack from Ubuntu 23.10 (Mantic Minotaur).
